Question

I am trying to select the src for the first img within the following post xml.

<post>
<regular-title>Testing 1</regular-title>
<regular-body>
<p>This is a test for projects on the website</p> 
<p><img src="http://media.tumblr.com/tumblr_m3t0r3saXy1rocfxw.jpg"/></p> 
<p><img src="http://media.tumblr.com/tumblr_m3t0s6bPyw1rocfxw.jpg"/></p>
</regular-body>
</post>

I can select the title and post text using php but I havent been able to select the img or its src.

$title = $xml->posts->post->{'regular-title'};
$img = $xml->posts->post->{'regular-body'}->??????;
$post = $xml->posts->post->{'regular-body'};

Am i using the right method to select the img or is there another way?

Answer 1

$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $xml->posts->post->{'regular-body'}, $matches);
$first_img = $matches[1][0];
if(!empty($first_img))
  return $first_img;
return 'no image url.png';

This should work just fine for you
